before my intercooler install and new intake install my idle on my d16y7 was at 650 and never fluctuated, after the intercooler install the idle is around 2000 and wont drop. my TB has been sticking lately and the vac reads 20 and 25 when under load which is normal but what could be my problem??

 

check your map sensor, throttle possition sensor, vacuum lines, etc.... any CEL's?

 

i always have a cel cause i dont have my 2nd o2 sensor in, where can i find the tps?
